3 Claims.

This invention relates to an improved attachment for adding machines andmore particularly to a. printing attachment for adding machines.

One of the objects of the present invention is the provision of animproved type of printing attachment adapted to be used in connectionwith various types of adding machines whereby the usual'paper strip usedin connection with adding machines has applied to one face thereof, a

0. series of printed indications which can be arranged in consecutiveorder throughout the length of the strip and is printed thereon prior tothe use of the strip for indicating thereon the various amounts to betotaled. I

Another object of the present invention is the provision of 1 an addingmachine attachment whereby the usual paper strip which is used forindicating thereon the numbers to be added, as well as the total, etc.,can have printed on the reverse side thereof various indications whichcan be used for adding purposes, whereby a merchant can advertise to thepublic his merchandise and disclose to the public an advanced notationof any sales or the like which are to be 2 carried out. i

A further object of the present invention is the provision of anattachment for adding machines whereby the usual strip of paper used inconnection with adding machines has printed or indicated thereon,suitable notations for the benefit of the merchant, or other party usingthe adding machine, and the same is applied to the side of the strip,which at the present time 7 is blank, and unused after being passedthrough the machine, so as to'utilize both sides of the paper andadvertise the merchandise of the merchant. V

With the above and other objects in view, the

,Figure 6 is a detailed side elevation'of the printing roll, showinganother application of the type; and,

Figure '7 is a detailed side elevation illustrating the application ofthe chains and sprockets in connection with the improved device.

Referring more particularly to the drawings, 1 indicates the body of aWell known type of adding machine, provided with the usual operatinghandle 2 which is attached to a rockable shaft ,3. Mounted upon thisshaft is an arm 4 connected with a link 5 which in turn is connected tothe bell crank 6. V

The bell crank 6 actuates the lever '7 attached to shaft 8 and mountedon thisshaft is a rockable member 9 which is adapted to: actuate theusual pawl 10 which engages the-ratchet 11. for rotating the feed roll12 for the usual paper slip upon which the indications of the machineare printed. The above is well known construction and forms no part ofmy invention.

Arranged at, the rear of the machine 1 is a frame 13 which supports theoperating mechanism for my improvement. This frame is connected by meansof a bottom cross piece 14 and a transverse bolt 15. A removablecover-portion 16 is provided and a removable side portion 17 closes theback of the frame and embraces the side portions thereof, as shown inFigure 1.-

The shaft 18 is carried by ,the frame 13 and supports a'paper roll 19.The paper on this roll is fed upwardly over the guide roll 20 and, thenextends'forwardly over the support 21 where it passes down around theroll 12.

Within the frame 13, an inking. roll 22 is supported which is preferablypositioned to be contacted by the type 23 in the type roll 24.

The rolls 20 and 22 are positioned in close' proximity to the type roll24, so that as the paper is fed from the roll 19 over roll 20, the type23 V will engage the inking roll22, and the paper, as it passes over theroll 20 for printing thereon various indications such as illustrated inFigure 2. The lines of indications which in the present instance areindicatedat 2.5, are arranged in equal spaced relation due totherelative position of the type with respect to the roll 24, and the evenrotation of this roll with the discharge of merchant desires to use.

teeth of the ratchet 29. This ratchet 29 is mounted upon the shaft 30which supports the' type roll 24. -The type roll 24 is yieldablyretained in engagement with the inking roll 22 and the guide roll 20, bymeans of spring members 31 which are arrangedupon opposite sides of theframe 13 as shown in Figure 4, and engage the shaft 30. The ends. ofeach spring are attached to the outside walls of the frame 13 at a pointbelow the uppermost position of the shaft 30, as shown in Figure 1,whereby the shaft 30, which is mounted within suitable slots in the sidewalls of the frame 13 will be urged downwardly.

The link 26 is yieldably retained in position with respect to theratchet wheel 29 by means of a coil spring 32 as shown in Figure 1 topositively assure engagement of the pin 28 with the teeth of the ratchet29 when link 26 is moved bers 34 can be positioned between the spacingmembers and yieldably retained in position.

Another form of type roll is illustrated'in Figure 6, wherein the maintype'rcll 24 has aremovable belt or endless portion 35 mounted thereon,and the type members. 36 are formed integral with the same.

This permits a number of'indications to be quickly applied totheexteriorof the roll 24, or removed therefrom. In Figure 7', I have illustratedanotherform of the invention wherein the ratchet 29 is replaced by meansof a-s pro'cket 37 'anda sprocket 38 can be mounted upon the supportingshaft of the roll 12 and these two sprockets can be connected bymeans ofa chain 39, illustrating that various ways can be provided forconnecting'up the type roll with the feed roll 12, so as to providesimultaneous action between these two rolls.

-As shownin Figures'S and 4, the-fram'e'l3 is normally enclosed bymeansof a housing 40 which can be set down over the frame, and thishousing is providedwith a' removable-cover portion 41. -A finger wheel42 is attached to the that I have provided a comparatively simple andinexpensive attachment for adding machines, wherein the usual blank sideof the paper which is used for'indicating the figures thereon, can

- have printed on the reverse side, which at the present time is blank,a series of advertising or any other similar type of notations which theFrom this it will be apparent that if a merchant contemplates a salewithin a day or two, or if he is' placing on sale merchandise at aparticularly low price, this can be indicated on theusual blank side ofthe paper an'ddi'scl'ose the facts to the purchasing public. f r Thetype onthe roll canbe' so'arrangedtha't either short or longstrips canbe torn from the machine,- but ;the advertising or indications thereonwill be so arranged as to intelligently indicate to the purchaser whatis being placed on sale, etc.

This device is inthe form of an attachment and can be readily connectedup to well known makes of adding machines on the market at the presenttime, with comparatively no change at all in the machine, and will provea great benefit to a merchant.

In order to maintain the attachment in close proximity to the machine 1,the brackets 43 are provided with lateral ears 44 and rivets 45 are usedfor connecting the frame 13 with these ears. The lower portion of theframe carries a lateral projecting arm 46 which extends beneath theadding machine and is attached thereto by the screw member 47.

While I have shown and described the preferred embodiment of myinvention, it will be apparent from the foregoing that slight changesmay be made in the construction when putting theinvention into practicewithout departing from the spirit of thesame'or the scope of theappended claims.

I claim:

1. An attachment for adding machines including a frame, means forsupporting the frame at one end of the'adding machine, a support for apaper supply roll carried by the frame, a guide rcllabove the supplyroll, an inking roll adjacent the guide roll, a printing -rolIpositioned above and in intimate contact with the'inking roll, and theguide roll, whereby to press upon the paper as it passes over the guideroll predetermined imiaressiohsjmeans for guiding the paperfrom theguide roll around the feed roll of an adding machineand manuallycontrolled means for simultaneously imparting movement to the type rolland the feed roll of the adding machine.
